A little old lady is walking down the street , dragging two plastic garbage bags with her , one in each hand . There's a hole in one of the bags , and every once in a while a $20 bill is flying out of to the pavement.
Noticing this , a policeman stops her...."Ma'am,there are $20 bills falling out of that bag..."
"Damn!" says the old lady...."I'd better go back and see if I can still find some.Thanks for warning !"
"Well,now , not so fast ," says the cop."How did you gett all that money? Did you steal it ?"
"Oh , no," says the little old lady ."You see , my back yard backs up to the parking lot of the football stadium . Each time there's a game , a lot of fans come and pee in the bushes , right into my flower beds ! So , I go and stand behind the bushes with a big hedge clipper , and each time someone sticks his little thingie through the bushes , I say :$20 or off it comes !"
"Hey,not a bad idea !" laughs the cop . "OK , good luck! By the way , what's in the other bag!"
"Well" , says the old lady , "not all of them pay up...."
